Consider a geosynchronous satellite system orbiting 36,000 km above the earth with a 100 Mbps data channel. How long does it take to send 4096 bytes of data from one earth station to another via the satellite? If we increase the transmission rate to 1.0 Gbps, how long will it take to send 4096 bytes?

Suppose you sent 46K bytes across a short RS-232 connection that operated at 19,200 bits/sec. How long would the transmission take? (hint: dont forget overhead bits.)

Consider a transmission system that provides 4000 Hz of bandwidth and uses 16 different values to encode the information. For an ideal system with no noise, what is the maximum data rate possible? If the system has 28 dB signal to noise ratio, what is the maximum data rate possible?
